Be. known that I", KARL HEINRICH Ros/arianna, a subject of the King of Hungary, and a resident 0f Frankfort-Onthe- Main, Germany, have invented a certain Iniproved Self-Closing Funnel for Liquids, ot

which the following isa specification.

The present invention relates to a funnel such as used fior. filling liquids into bottles and the like, and of the kind provided with a float-valve adapted to intercept the supply of liquid as soon as such liquid rises into the neck of the bottle. Y

According to the present invention, the floatvalve is guided on the inner ends of pins passed through the walls of the funnels stem. The heads of said pins are adapted toL slidably guide a sleeve on the stem so that a passage is formed between these elements for the discharge of displaced air. A bridge in the lower part of the sleeve serves as support for the tunnel and also for the bottom valve, the latter being opened when the funnel is placed in the bottleneck and closed when it is lifted. The tail-piece of the bottoni valve is guided in the supporting bridge, and the body of the valve is provided with radiating pins by means of which it is guided in the stein.

The invention is illustrated in the anneXed drawings, Figure I representing a longitudinal section through the funnel, the valves being open, Fig. Il, a view of the lower part of the funnel, seen from the f left of Fig. and Fig. III, a view of the lower part of the funnel, seen troni the right of Fig. I, it being inserted in the neck of a bottle.

In said drawings, a is the funnel-bowl and I) the stem connected thereto. A iioat-valve c, having a cone at its upper end, is loosely fitted in the stem and adapted to close the funnel when raised with its cone against a valve-seat h mounted in the upper part of the stein. The valve c is guided at each of two places on the ends of four pins Z which are fitted at right angles in the walls of the stem so as to support the valve on four sides. The heads of said pins are situated on the outside of the stem and serve as guides for a sleeve e adapted to slide upon the stem. in the lower part of the sleeve e a slot if: is provided through which a lug L, connected to the stein Z), projects. Slot and lug allow a displacement of the elements through the distance m.

sleeve and the stem and is ln making the slot k in the sleeve c, the strip stamped out of the saine is only detache/.Cl at 'the top and. at both Sides., the strip, being thereupon bent across the sleeve to form a bridge a. Theouter end of the Strip iS Passed throne-l1, a Slet 0 Italia @PPO- site` walloifthe sleeve and connected thereto.

A seat g. for a dropwvalve F is provided in the lover Part 0f the stem Said; valve having a shouldered tail-piece by means of which it is attached to the bridge n. Radiat? ing pins m3 on the valve body guide the upper part of the latter in the stein Z1, A cross-pin r in the stem limits the upward movement of the valve F and the downward movement of the valve c.

rlfhe funnel proper is siipported on the bridge a which bears against the lower end of the stein o, and the whole arrangement is supported on the mouth of the bottle neck by means 0f a Hanse provided O11 the upper end of the sleeve c. While the funnel is supported on the bridgen, the valve F, owing to the shoulder of its tail-piece being engaged by the bridge, is raised away from its seat, as shown in Figl.

Above the valve seat i a strainer is provided to prevent the entrance of impurities intol the stem.

Vhen the funnel is disposed in the bottle neck P, as shown HI, the valves have the position asI shown Fig.v l. Liquid poured intoJ the bowl a passes through the stein and is discharged by the lower tapering end of the sleeve e into the bottle. The air displaced by the liquid passes through the slot 7u along the passage between the discharged at the nozzle t of the sleeve. As soon as the liquid rises from the bottle into the neck, the float valve c will be lifted up against its seating 7L so as to stop further tlow of liquid. When the funnel is lifted from the bottle, the sleeve drops on the stem until the lug L engages the upper end of the slot c. This allows the bottom valve F to drop into its seating so as to prevent the liquid contained in the funnel from being discharged unt-il the funnel is placed in another bottle.

Very little friction is produced by the guide pins on the valves so that a niost satistactorily working device is obtained by the arrangement.

I claim 1. A funnel for filling bottles comprising Cil a funnel-bowl, a stem connected thereto, projections within said stern, a float-valve fitted in the stem and guided on the inner ends of said projections, a valve seat in the upper part of the stem for receiving the valve and closing the funnel when said valve is raised, means for discharging the displaced air, and means for closing the lower end of the lstem when the funnel is removed from the bottle, substantially as set forth.

2. A funnel for filling bottles, comprising a funnel-bowl, a stem connected thereto, a float-valve arranged in said stem so as to close the funnel, pins fitted in the walls of the stem and adapted to guide said valve with their inner ends, a sleeve slidably fitted on the stem and guided on the heads of said pins so as to leave a space for the discharge of the displaced air, a flange at the upper end of the sleeve for supporting the funnel on the mouth of the bottle-neck, a bridge in the lower part of the sleeve for supporting the stem, and a drop-valve in the lower part of the stem supported on said bridge so as to open when the funnel descends in the sleeve and close when it is lifted, substantially as set forth.

3. A funnel for filling bottles, comprising a bowl, a stem connected thereto, a floatvalve in the stem adapted to close the funnel, pins in the walls of the stem to guide the valve with their inner ends, a sleeve slidably fitted on the stem and guided on the heads of said pins to provide a passage for the displaced air, a lug on the lower part of the stem guided in a longitudinal slot in the sleeve, a bridge in the sleeve formed by bending the'strip cut out from said slot, a bottom-valve in the stem guided with its tail-piece in the bridge and supported thereon so as to open when the funnel descends in the sleeve and close when it is raised, and radiating pins on the body of said bottomthe non-buoyant valve upon the insertion of the spout into a vessel, as described.

5. A spout having perforated rings form;- ing oppositely disposed valve seats, a tubular buoyant valve incased in the spout adapted to close the upper ring, a sleeve incasing the spout and connected thereto to permit limited relative movement, and a non-buoyant valve in the spout adapted to be unseated by the movement of the spout relative to the sleeve upon the insertion of the spout into a vessel.`

6. A spout having perforated rings forming oppositely disposed valve seats, a tubular buoyant valve incased in' the spout adapted to close the upper seat, a sleeve incasing the spout and connected thereto to permit limited relative movement, a non-V buoyant valve and stem therefor, and an integral portion of the sleeve supporting said valve when it is opened.

7. A spout, a slidable sleeve thereon having an upper flange and a lower instruck finger providing a slot, a valve seatV in the spout and a non-buoyant valve therefor, guide fingers for said valve, a valve stein having a projecting flngerpassing through said instruck finger, and a lug on the spout working in said slot, as and for the purpose described.
